Background.
We believe that, in patients with Parkinson’s disease (PD), a forward-directed increase in the subjective vertical position (SV) leads to prolonged worsening of forward flexion of the trunk (FFT) mainly because the body adjusts to the SV.
We conducted a study to clarify the relation between the SV angle, FFT angle, and various other clinical measures by comparing baseline values against values obtained 1 year later.
Methods.
A total of 39 PD patients (mean age, 71.9 ± 10.1 years; disease duration, 7.2 ± 5.4 years; modified Hoehn & Yahr (mH&Y) score, 2.6 ± 0.7) were enrolled.
The Unified Parkinson’s Disease Rating Scale score, Mini-Mental State Examination (MMSE) score, mH&Y score, FFT angle, SV angle, and levodopa-equivalent dose (LED) were assessed at the time of enrollment (baseline evaluation) and 1 year later.
Results.
Eighteen patients (46%) complied with the protocol and completed the study.
Significant increases were observed in the 1-year SV angle (p=0.02), MMSE score (p=0.008), and LED (p=0.001) compared to baseline values.
Correlation was observed between the baseline SV angle and baseline and 1-year FFT angles (r=0.64, p=0.008 and r=0.58, p=0.012, respectively) and between the 1-year SV angle and 1-year FFT angle (r=0.63, p=0.005).
Conclusion.
Our data suggest that the SV contributes to increased FFT.
